Binance halted trading on aBNBc tokens, as well as on HAY tokens, a stablecoin project that was subsequently exploited. Ankr also tweeted that "We have been in touch with the [decentralized exchanges] and told them to block trading", although decentralized exchanges are typically not supposed to be able to "block trading".
This serves as a good example of how theft amounts shouldn't be naively calculated based on the token price before the theft × the number of tokens stolen. $FLARE was priced at around $18.25 before the attack, and a naive calculation would place the theft amount at $71 billion. However, the lack of liquidity caused the token price to plummet to $0.0000018, and the attacker ultimately ended up with around $17 million.
The total funds stolen appear to be around $4.17 million, according to analysis by SlowMist.
An FTX account administrator wrote on the FTX support Telegram, "FTX has been hacked. FTX apps are malware. Delete them. Chat is open. Don't go on FTX site as it might download Trojans". The message was pinned by FTX General Counsel Ryne Miller.
Miller later wrote on Twitter, "Investigating abnormalities with wallet movements related to consolidation of ftx balances across exchanges - unclear facts as other movements not clear. Will share more info as soon as we have it."
A Telegram admin subsequently wrote, "Not all hope is lost. Engineers have managed to retrieve substantial amount of funds," but no details were provided beyond that. A later announcement by Miller claimed that FTX had "initiated precautionary steps to move all digital assets to cold storage", suggesting some of the transfers may have been a part of that effort.
Many speculated that the so-called hack had been coordinated by insiders.
Analysis by the crypto security firm SlowMist attributed the theft to a compromise of Shen's seed phrase. Shen had been using the Trust Wallet software, though the theft does not appear to be related to security issues with the wallet software.
